When using PHPbrew you might sometimes need memcached, there is an error that happens when you try and install it with the following command:
phpbrew ext install memcached stable -- --disable-memcached-sasl
The error appears such as:
===> Configuring... Error: Command failed: ./configure '--disable-memcached-sasl' --with-php-config=/home/afigueira/.phpbrew/php/php-7.2.0/bin/php-config >> /home/afigueira/.phpbrew/build/php-7.2.0/ext/memcached/build.log 2>&1 returns:
To solve this, make sure you have libmemcached installed on Ubuntu.
sudo apt-get install libmemcached-dev
Hope this helps anyone that gets stuck with this error!
